  • Measure resistance to ground.
  • Result: 0.2 Ohms – a dead short.

1.3 "94V-0" – The Safety Rating

This is a UL (Underwriters Laboratories) flammability rating. 94V-0 means the printed circuit board material (typically FR-4) self-extinguishes within 10 seconds after being subjected to a flame. While irrelevant to circuit tracing, this marking confirms the board meets international safety standards, implying it is a production-grade board, not a prototype.
